Question

Work out the velocity v at the end of a rollercoaster ride (0). (rearrange the equation for KE to make velocity v the subject)

KE=1/2mv^2

Answer 1

Step-by-step explanation:

If the kinetic energy of an object is given and we need to find its velocity of motion, then we can find it by using the formula of kinetic energy as :

`K=(1)/(2)mv^2`

m is mass of the object

We can rearrange the above equation such that,

`v=\sqrt{(2K)/(m)}`

Hence, this is the velocity at the end of a rollercoaster ride.
